$150? I'm very surprised to hear that...especially when it's not the actual switches that are the problem.

My DAC 3 buttons were becoming sticky and non responsive so i bought a can of electrical contact cleaner, took the unit apart and sprayed all the buttons on the main boards with it. After putting everything back together, it's working perfectly again.

The cleaner cost me about £4 gbp and time to dismantle, clean and reassemble was about an hour all in.

Did you ever figure this out? My Cue/Play buttons have gotten to where they don't react half the time, which is very annoying. I took the screws out of the top plate, hoping it would just come off and then I could clean under the soft-touch buttons, but it didn't. I took the screws out of the side and was able to remove the enclosure, but didn't see an easy way to get to the buttons. (It looks like you have to remove the little "C" clips from the end of the axle which the jog wheels attach to in order to remove them). I just put it back together until I can find more instruction.

You just need to clean the video heads. You can get a tape cleaner for this, or you can do it manually.

To do it manually and it's the better option. You will need a can of Servisol Video 40 (from places like Maplin or on the Net). Some cotton buds.
Remove the top cover of the video. Once done, spray all the parts the tape touches with Servisol. Wipe any visible dust and dirt away with the buds.
Concentrate the spray to the big video head. That should look clean when done.
Leave to dry, it won't take long and try a video. If you can see the picture, but it is breaking up or has "sparkles" on the screen. Then clean the head again till it is a clear picture.

Notes: don't clean with a tape in the machine.
If you don't know which parts the tape touches. With the lid off and powered on play a video. And watch where the tape goes.
It will take longer to clean the video if anyone smokes in the room where the video is kept.
I repeat NEVER put a tape into the machine till the deck is dry.

First try playing a CD. If that too skips you can clean the lens by opening it.Dust on the lens will effect all types of disc and will not be selective.You can buy a lens cleaning disk from any Cd store and play it to clean.The cleaning action takes place only if the disc rotates, so keep the top lid off to see if it rotates.If you have crossed 500 hours of playing may be the lens is due for a change.

to change headphone track, use the cue slider which is located on the right of the control panel above the right chanel treble control and below the cue gain control. chanel 1 or 2 can be selected or in the middle for a mix of both tracks just like the cross fader.

If you sure that the system supports the disc's format, the disc is clean, and its the right region.. try to clean the DVD lens.
DVD lens cleaning discs:
Every CD, stereo equipment, department, discount, store - and even sidewalk venders - carries CD lens cleaning discs. Are they of any value? Can they cause damage?
I generally don't consider CD lens cleaning discs to be of much value for preventive maintenance since they may just move the crud around. However, for pure non-greasy dust (no tobacco smoke and no cooking grease), they may not hurt and could even do a good enough job to put off a proper cleaning for a while longer.
However, it's also possible they will ruin the lens. Consider that the worst thing to do to a precision optical surface is to wipe it with a dry cloth as this is likely to scratch the surface as it rubs the dust over it. To the lens, a speck of dust is like a boulder. Once the lens is scratched, replacement of the entire optical pickup is the only remedy. And, since there are absolutely no sorts of standards for these things, it is possible for a really poorly designed cleaning disc to damage the lens even if the dust itself is non-abrasive. In addition, if the cleaning disc doesn't look like a CD to the optical pickup or disc-in sensor, the lens it may not even spin. So, the drawer closes, the drawer opens, and NOTHING has been accomplished! (But at least no damage will be done.)
As if this isn't enough, NEVER put one into a high-X CDROM (DVD player or DVDROM drive). The high speed rotation may cause the cleaning disc and/or player/drive to self destruct. And, don't try a cleaning disc on an automotive CD player that sucks in the disk - it will get stuck.

Is this happens on every disc? The NO PLAY message appears when "The disc that this unit cannot play is loaded (from the user guide)".
Maybe it's something to do with the DVD region?
If you sure that the system supports the disc's format.. And it won't play other discs... try to clean the CD lens.
